ing Devices. ot which the tollowingis e specifcetion.

My invention relates; to means for center- 10 ing or aligning the molds in a glass forming machine. and partcularl);Y to centeringr pins arranged to centei1 or aligrn the blank molds and liniehing molds with the neck molds.

ln machines of the type to which. Inv in l5 vent-ion herein. shown appliedF a body blank mold and a neck mold are brought together to torni a parison mold into which the glass is drawn by suction. Laten the blank mold is Withdrawn end replaced bv e inisl'iing' mold in which the bottle or other `glass article is blown to its 'linished torna While the neck end of the article is still retained in the neck mold.

lt is important to maintain the blank mold and the finishing' mold in exact alignment With the neck mold duringY the lnntliering and blowing operations respecti velvn in order to prevent defects in the finished ware. It is customary to reniovably mount the various mold sections in snp'- ports or holders which permit a limited amount of rotative movement ot said sections. @auch rotative movement is not e. serions objection Where the usual single molds are employed but becomes a serions objection when plural molds are used that is, molds having a plurality of mold cavities. as'eny such rotative movement ot one mold `port relative to another throws the mold cavities ont ot alignment. An object of the present invention is to provide irnalignment and prevent any such relative movement.
